Description

Options are OS Control, Custom, and

Maximum Performance. The BIOS pre-

configures the power settings on this screen as

follows:

• OS Control sets the processor power to OS

DBPM, the fan power to Minimum Power,

and the memory power to Maximum

Performance. In this setting, all processor

performance information is passed from the

system BIOS to the operating system for

control. The operating system sets the

processor performance based on processor

utilization.

• Maximum Performance sets all fields to

Maximum Performance.

• If you select Custom, you can configure each

option independently.
